IMPROVEMENT IN FIRE-EXTINGUISHERS.

To all whom 'it may concern:

Be it known that I, CHARLES T. HoLLo- WAY, engineer, of the cityr ofBaltimore and State of Maryland, have invented certain Improvements inFire-Extinguishing Apparatus, of Which the following is a specification;and I do hereby declare that the same is a full, clear, and exactdescription of my said invention, reference being had to theaccompanying drawing and to the letters of reference marked thereon.

My invention relates to that class of reextinguishers in which waterstrongly impregnated with carbonio-acid gas is theextinguishing agent,and the expansive force of the gas the motor to eject thegas-impregnated Water from the machine when it is desired to do so; andconsists in the improvements hereinafter set forth and fully described.

In the accompanying drawing, formingapart of this speciiication, Figurel is a sectional elevation of an extinguisher having my improvementsthereupon as elemental features. Fig. 2 is a part sectional and partnonsectional elevation of the same, as viewed from a different point.

Similar letters of reference indicate similar parts of the invention inboth figures.

A is a cylindrical vessel, designed to hold the solution of soda inwater. B is an outer globe, the interior of which is connected with thevessel A by the opening c. C is an inner globe, adapted to hold theacid, having the opening b closed by means of the stopper c, which isgrooved to increase its elasticity, and held down bythe cap D. Thepivots or journals upon which the globe C moves are represented by g andg. E is the handle controlling the movement of the globe G, the end ofhandle being secured by the socket d resting on the spiral spring e, andsliding on the pin e. F is the packing-box with the gland j'. G is a capclosing an opening in the top of the vessel A; and H, a cock regulatingthe ilow of the gas-impregnated water from the vessel through the hoseI.

The operation of my extinguisher is as follows: Supposing that themachine is to be charged and made ready for use, the handle E is securedin the position shown, the caps D and G are removed, and the stopper cWithdrawn. NVater is then poured into the vessel A until it is nearlyfilled, when the soda is added. The acid is then introduced into theglobe C, the stopper placed into position, and the caps replaced. Theapparatus is then in condition to remain unused for any length of time,no part thereof being subjected to any pressure. In the emergency offire occurring and the extinguisher is to be brought into requisition,the handle E is turned up, the position of the globe U is inverted andthe acid emptied into the vessel A, where it is at once neutralized uponmixing with the soda contained in the water. Carbonic-acid gas is thusgenerated or produced, and, not being able to escape, forces the entirecontents of the vessel A through the cock H when opened.

The advantages I claim are cheapness, simplicity, and strength ofconstruction, and ready and efficient adaptation to the purpose forwhich the apparatus is designed.

Having thus described my invention, what I claim as new, and wish tosecure by Letters Patent, is-

The combination of the globes B and C, stopper c, cap D, and handle Ewith the socket d as attached to the cylindrical vessel A, substantiallyas and for the purposes herein set forth.
